'SCRAPER.

Application filed May 5, 1925.

T 0 all whom it may concern Be it known that I, OSCAR FANBERG, a citizen of the United States, residing at Hensley, in the county of McDowell and State of IVest Virginia, have invented a new and useful Scraper, of which the following is a specification.

This invention relates to a scraper designed primarily for use by coal miners. IVhere machines are employed for mining coal, considerable dust collects in the cuts.

and it has been the practice heretofore to use a shovel for removing the dust. Shovels, however, are awkward to handle for this purpose and are not efiicient betause the dust is often forced back into the cut'where it can not be readily withdrawn.

It is an object of the present invention to provide a simple and efficient tool which can be inserted readily into a cut, the blade of the tool sliding easily over the dust during the insertion. When the tool is withdrawn, however, the blade will operate to engage and drag the dust from the cut.

With the foregoing and other objects in view which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings,

Figure 1 is a plan view of the device.

Figure 2 is a section through the blade on line 22 Figure 1.

Figure 3 is a view similar to Figure 2 showing the blade opened for scraping.

Referring to the figures by character of reference 1 designates an elongated handle Serial No. 28,183.

from one end of which are extended forwardly diverging arms 2 connected by a cross rod 3. This rod is extended through bearing brackets 4 riveted or otherwise atta hed to the concave face of an elongated concavo-convex blade 5. The lower edge of this blade is straight and reduced or sharpened as indicated at 6. The brackets 4 are attached close to the opposite longitudinal edge of the blade and at opposite sides of the center thereof. A wing 7 is fixedly connected to and extends radially from rod 3 at a point between the bearings .and constitutes a stop against which the upper portion of the blade will thrust during the scraping operation. This will be apparent by referring to Figure 3.

In using the tool the same is thrust forwardly into the cut and during this operation the blade is folded under the arms 2 so that its convex face will glide over the bottom of the cut and the dust accumulated hereon. By then pulling on the tool the lower longitudinal edge 6 will engage the bottom of the cut and the blade will as sume itsscraping position as shown in Figure 3. Consequently the dust in the path of the blade will be withdrawn from the out quickly and effectively.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signa OSCAR FANBERG.
